As background, I installed an opening port on Imzadi to replace a fixed aluminum framed portlight, and it didn't go to my expectations. I had to expand the existing opening by a small margin, and decided that I could use my handy dandy Dremel tool to cut the fiberglass laminate. But the cut I got was far from smooth and straight. So I decided I'd put off installing the other three ports until I figured out a better way of doing it.
I have three current projects that will require me to cut laminate: additional opening ports, removing the inner skin on the cockpit locker covers so I can replace rotted core, and making a propane locker. So my question is: What would be the best tool for getting smooth straight cuts in fiberglass laminate? A friend in the boat repair business will loan me his Rotozip, but I'm not confident that I would get better cuts that I did on the window opening (operator error, I freely admit). Dremel (among others) makes a mini circular saw that looks almost ideal for making shallow, straight cuts. But corners might be a problem. A vibrating multi-tool (I still think of it as a Fein tool) seems like a real possibility, plus having a lot of uses on other projects. But I'm not sure how well it will cut fiberglass. You guys are the experts. What tool should I buy (or borrow)? Rick Brass Imzadi C&C 38 mk 2 la Belle Aurore C&C 25 mk1 Washington, NC
